Review Summaries
In the detailed review on 6moons, the CA-339 (original version) is explored with great admiration. The reviewer notes the design’s excellence, the build quality, and calls the amplifier “formidable brute with high class.” The review also points out slight coloration in the uppermost treble in some recordings and suggests that the MK-II’s design refinements respond to such minor traits. 6moons
Another 6moons segment describes how the push-pull 300B architecture used in the CA-339 helps preserve much of the 300B’s tonal character while delivering significantly more power than typical single-ended 300B designs. The reviewer found that the bias control and stability help maintain consistency over long use. 6moons+1
